3738841 - Equals filter on custom field returns no results in enterprise project api/app - s/4hana cloud public edition

You have created a custom field and populated it on an enterprise project.
Then you detected that filtering by the custom field using equals in the "Project Control – Enterprise Projects" app or API returns no records.
Using contains for the custom field returns the expected project.

SAP S/4HANA Cloud Public Edition

We found two formats stored for the custom field in the CDS view:
'000XXXXX49' (10-character, leading zeros)
'XXXXX49' (7-character, no leading zeros)
Because of this inconsistency, condition eq may not return the expected record. 

As a workaround, you could use the following request avoiding the eq issue:
…/sap/opu/odata/sap/API_ENTERPRISE_PROJECT_SRV;v=0002/A_EnterpriseProject?$filter=(startswith(YY1_CustomFieldName,'XXXXX49') and endswith(YY1_CustomFieldName,'XXXXX49') &$format=json&$inlinecount=allpages
