FIX - FIORI F2499 Manage Customer Materials – Unable to load the data error

[zenithltd1]

Problem

I the Unable to load data error in FIORI app F2499 in S4CORE 102 (1709) and UI UIS4HOP1          300 (S/4 HANA Premise). The fix actually took longer than expected and hence I am writing this blog for others who will bump into similar issues.



Approach

I checked Fiori apps library and made entries in SICF for the UI APP (Front End or FE) and Odata service in /IWFND/MAINT_SERVICE (Back End or BE). They were all there.

Checked F12 and saw the following message

caught (in promise) Error: Could not load annotation URL: "/sap/opu/odata/IWFND/CATALOGSERVICE;v=2/Annotations(TechnicalName='SD_F2499_CUSTOMER_MATER_ANNO_MDL',Version='0001')/$value/?sap-language=EN&sap-client=800"

 



Search in OSS with annonation or F2499 did not yield good results.

2558344 - Fiori tile, "Unable to load the data"

 

Checked /UI2/FLIA with indent CustomerMaterialInformation-manage.

Indent (Semantic Object-Semantic Action)  can be found in the Target Mappings in the Fiori Apps Library or in the URL.

URL - https://s4hana:8001/sap/bc/ui5_ui5/ui2/ushell/shells/abap/FioriLaunchpad.html?sap-client=800&sap-lan...

Nothing unusual here.



 

I imported catalog SAP_TC_CEC_SD_COMMON using

SE38 /UI2/GET_APP_DESCR_REMOTE_DEV. Still got the same error.

 

I got a break with gateway error log /IWFND/ERROR_LOG. There were 2 messages

/IWFND/MED220

Vocabulary Annotation File 'SD_F2499_CUSTOMER_MATER_ANNO_MDL' version '0001' not found on SAP GW Server

2525434 - Vocabulary Annotation File not found on SAP GW Server

/IWFND/MED033

No existing service group found for service group identifier ''

 

Based on Ist message, I did all the steps in 2525434  including regen of project SEGW (BE). However it did not solve the issue.



I cleared caches

1. 
   
   
   
   1. /IWFND/CACHE_CLEANUP in gateway system
   
   
   2. /IWBEP/CACHE_CLEANUP in backend system
   
   
   
   

Re-index with /UI5/APP_INDEX_CALCULATE for one app did not solve the problem either.

The second error pointed to an unusual setting.

2739082 - S4HANA 1809OP : the service SD_CUSTOMER_INVOICES_MANAGE metadata cannot be loaded

This called for SICFing LO_VCHCLF which is for Variant Config service. Do not know what the relationship between VC and CMIR is. However adding service fixed the issue.

App started working and I am able to see CMIRs.



Conclusion

The steps outlined are for fixing F2499. However. the approach can used in solving other FIORI apps as well.
