How to find out the database table field behind a FIORI app field based on example FIORI app “Make Bank Transfer”

Introduction:

Sometimes it is required also for a functional consultant to know which database table field is behind a native FIORI app field (e.g. for troubleshooting). Unfortunately, I could not find much helpful information regarding this topic on the net. Therefore, after investigating on that topic I would like to share with you an easy guide on basis of FIORI app “Make Bank Transfer” (Fiori ID: F0691) as an example how you can manage to find out the database table/ database table fields behind a FIORI app.

Problem:

Find the database table field behind FIORI field “Paying Bank Account” within FIORI app “Make Bank Transfer”.

Solution:

1. Go to SAP Fiori Apps Reference Library and find FIORI app “Make Bank Transfer” (Fiori ID: F0691). Go to “Implementation Information” and then to “Configuration”. Find the relevant OData Service(s) without a …* and copy it to your clipboard.

2. Go to GUI transaction /nSEGW (= SAP Gateway Service Builder) and open FCLM_CASH_BANKTRANSFER (without ending _SRV). Here you have all the details regarding the OData Service.

3. Go to Data Model > Data Source References > Exposures via SADL (confirms that FIORI is based on CDS views which most of the recent FIORI apps developed by SAP are) > Entity Types. Now, find the FIORI app field “Paying Bank Account” in one of the Entity Types within Properties.

In our case C_CashRepetitiveCodeVHType is which we are looking for, copy it to your clipboard.

Please note: In ABAP Field Name information you can see the associated type used within FIORI app and type details like type kind, length and decimals.

4. Go to SE80 > Development Object and search for C_CashRepetitiveCodeVH (without ending TYPE). Choose Data Definition.

5. If you go to CDS database view CMKBTTMPLVH now, you can see the table/ view used for CDS view field “PAYINGBANKACCOUNT”. Double-click on table until you reach the database table behind the initial CDS view.

Outcome:

We found out that behind FIORI field “Paying Bank Account” in FIORI app “Make Bank Transfer” (Fiori ID: F0691) is database table: FCLM_BAM_AMD with according field ACC_NUM. Also, data element, data type, length and decimal information are provided in this screen.

Please note: This procedure can also be used to find out tables/ structures and FIORI field lengths behind FIORI apps.
