How ALE and IDocs Affect SAP In-House Cash Configuration

Become familiar with the configuration of the Application Link and Enabling (ALE) settings of SAP In-ouse !ash"#ollow a step-b$-step technical implementation of ALE to enable the structured e%change data &ia Intermediate'ocuments (I'ocs) within SAP In-ouse !ash" Become familiar with the most important I'oc t$pes and their usein SAP In-ouse !ash" nderstand how $ou can test the correct ALE configuration within the SAP s$stem"

Key Concept

SAP In-House Cash allows corporate cash and treasur$ management departments to set up a pa$ment factor$and to centrali,e their pa$ment flows" ne of the challenges is that the business processes of SAP In-ouse!ash span multiple financial components and re.uire a broad set of business and technical skills"

SAP In-ouse !ash can help corporate treasurers or cash managers get a faster o&er&iew of their li.uidit$ positionand achie&e a higher degree of transparenc$ of their cash flows" *ultinational organi,ations can centrali,e theirgroup cash flows and establish an in-house bank" In most cases SAP In-ouse !ash is deplo$ed on a separateinstance than SAP E/P #inancials and has to be connected to &arious other SAP s$stems within the group" 0oenable the structured e%change of data between distributed SAP (or non-SAP) s$stems+ SAP In-ouse !ash usesApplication Link Enabling (ALE)" It is the technical basis for SAP In-ouse !ash+ but &er$ few SAP professionalsare familiar with this technolog$ and the necessar$ settings to configure SAP In-ouse !ash" I1ll pro&ide a step-b$-step introduction to e%plain these settings and make $ou familiar with some of the ALE and Intermediate 'ocument(I'oc) basics to better understand the configuration of SAP In-ouse !ash"

Some ALE and IDoc asics

0here are essentiall$ two wa$s to technicall$ link two SAP s$stems &ia ALE

8" If the s$stems are independent+ $ou implement a loosel$ coupled technical integration" In the case of acommunication error or if the called s$stem is una&ailable+ the calling s$stem can continue to work" In thiscase+ s$stem-to-s$stem communication is happening largel$ on an as$nchronous basis and messagesare e%changed between the s$stems" 0he data format that the SAP s$stem uses for the as$nchronousALE communication is called I'oc" 0he technical communication between SAP s$stems is based on

transactional /emote #unction !alls (t/#!)"5" If $ou decide to establish a narrow coupling between SAP s$stems $ou re.uire the called s$stem to

alwa$s be a&ailable" 0he technical basis is s$nchronous calls of a remote-capable function module in thetarget s$stem" Such s$nchronous calls are suitable for &erif$ing or reading data in other s$stems"

Since the SAP In-ouse !ash business scenarios are not suitable for the narrow coupling shown in option 5+ I1llfocus on the first option in this article"

SAP In-ouse !ash is based on as$nchronous communication that takes place between SAP In-ouse !ash+ theSAP s$stem with the general ledger of the head.uarters+ and the SAP s$stems of the subsidiaries with the

respecti&e financials s$stems" Some of these s$stems ma$ not e%ist in $our s$stem landscape (e"g"+ if $ou decideto run the SAP In-ouse !ash s$stem and the general ledger on a single instance)+ but the basic ALEconfiguration is alwa$s the same"

0he data format that is used for as$nchronous ALE communication between logical SAP s$stems is the I'oc" AnI'oc represents a configuration of an I'oc t$pe that determines the I'oc structure and indicates the SAP dataformat that is used to transfer the data for a business transaction" Each I'oc consists of a header+ se&eral data

segments+ and status records" 0he I'oc header contains the contents+ structure+ sender+ recei&er+ and currentstatus of the I'oc"

Each data segment contains a standard header consisting of a se.uential segment number+ a description of thesegment t$pe and a 8666 character long string field containing the actual data of the segment" 0he status recordsshow the histor$ of the s$stem processing steps applied to the I'oc so far" 0he format is identical for each I'oct$pe"

9ou can displa$ I'oc t$pes b$ following this menu path 0ools : ABAP ;orkbench : ALE : ALE 'e&elopment :I'oc 0$pes" 9ou use the following I'oc messages and message t$pes for the communication between SAP In-ouse !ash and other SAP s$stems

ALE Configuration in the SAP System of the Su*sidiary

0he same si% steps that I showed $ou are re.uired to configure the ALE settings in the SAP s$stem of thesubsidiaries that communicate with SAP In-ouse !ash" 9ou ha&e to make these entries for inbound andoutbound message t$pes for each subsidiar$ compan$ that communicate with SAP In-ouse !ash"

0he first fi&e steps are similar" 0he onl$ difference is that $ou enter all settings for the subsidiar$ instead of thehead office" In step $ou need to create onl$ one partner profile for B (bank)" 9ou ha&e to create the in-housebank with transaction #I!" 9ou can1t create these partner profiles for the in-house bank if $ou ha&en1t first createda house bank with transaction #I85" 0he partner t$pe settings for B are the same as abo&e with BP" 9ou need tocreate an inbound parameter for the message t$pe #I

0he settings for the business partner t$pe LS (logical s$stem) are the same as for the business partner t$pe B and$ou can simpl$ cop$ them" If the subsidiar$ is in the same s$stem as SAP In-ouse !ash+ $ou basicall$ send
