Function module for error: ME045 G/L Account XXXX cannot be used

Dear SAP Colleagues,

I was trying to do a pre-validation of G\L account while creating a MM document like PR or PO.

Normally this error happens when the cost object such as cost center or WBS or Asset and the G/L account were not mached as per the Field Status Group under FS00 data.

Can I know any standard function module available to carryout this validation?

Or can I know in which table this FS00 data would be stored?

This would be more helpful for me to build the custom logic as per the requirement.

Thanks in Advance.
