SAP-Where-Used list not working on Cloud System

[5352119c]

REASON

The where-used functionality for sap objects in customer cloud systems is generally not supported. Therefore, the where-used is generally probably not supported in that system .

The where-used lists are based on index data stored in tables - the "Update Navigation Index" option fixes it for an individual program if that program's index entries are corrupted in some way.

( path : Utilities->Update Navigation Index)

 

Solution

If there are lots of items incorrect and the where-used for SAP objects is required in this system for some reason, you have two tools to fix the where-used list problem. There are 2 programs for this - SAPRSEUC to rebuild customer object indexes (Y & Z) and SAPRSEUB to rebuild SAP object indexes. As mentioned, rebuilding the index table content is a very time-consuming operation. Consider it may run for a day for customer objects, and might more days or a week for SAP standard objects. you'd better Schedule reports in background job to fix it .

But If there are many DDLS objects missing in the where-used result, please run the report SDDIC_DDLS_INDEX_ALL_SOURCES to rebuild the RIS indices for all active DDLS objects .These actions should only be executed in a customer development system., maybe you can according to the Note：2833335 - DDLS object missing in the where-used result list - SAP ONE Support Launchpad

Customization

If you just want to rebuild some specific DDLS, you could add the DDL that you need into table 'DDL_OBJECTS'.

Logic in the report SDDIC_DDLS_INDEX_ALL_SOURCES:

step1 ,get all DDL sources from the table DDDLSRC, just rebuild customer object indexes (Y & Z) when you input 'CUS' at select-screen

get DDL sources

step2, Get CDS View Sources: cl_ddls_where_used=>usage_finder->resolve( i_ddlname ), the ddl sources are saved in the table ddddlsrc . Then, they will be converted into Standard table

Class: CL_WB_DDLS_RIS_INDEXER, Method: IF_WB_DDLS_RIS_INDEXER~WRITE_USAGE_REFERENCES, insert into table 'ddls_ris_index'
