Hi Muhammad,
Please check the next link:
FPG1: FI030 Error accessing function module: FMFPO_READ_QUICK - Utilities Industry - SCN Wiki
Mentions the next solution:
There are different options to solve this issue. Please read the following points very carefully to find out which option is the correct one for your company:
- If the FM fields are not active (structure SI_FKKFMOP is inactive resp. global state of switch FICA_FM is off) then it seems that your company doesn't want to use the Funds Management Integration. In this case it is possible to deactivate the update in Funds Management for the affected company code with view V_T001_FM2 (field T001-XFMCA). Please note that the data won't be updated into FM afterwards!
- It is possible that the workaround of SAP note 569257 was used in the past. Therefore please read this note very carefully and clarify internally if this solution was really used in the past.
- If it's required to activate Funds Management retroactively then please note that this option is not possible in an already running system! Please pay attention to the long text of SAP note 686383. There you can read the recommendation to contact the SAP Consulting Department because it is required to fill all already available data with corresponding dummy account assignments.
But if you have a S4Hana, you need to activate the business functions: FICA_FM (Funds Management Contract Accounts Receivable and Payable).
