Set currency 3 digit decimal format

Dear SAP Experts,

Currently we have multiple SAP clients running in multi countries in one platform and shared SAP cross-table

Now we have situation that one new country will have 3 digit decimal currency format OMR (150.876). At the moment if

change decimal currency setup in table V_CURX then we can face issue with other clients.

Case1 - I understand if no document posted currency in OMR is any of the client no issue I assume.

Case2 - If there is any document posted with currency OMR in any of the client which shared cross client table then we might

get serious implications.

Is there any way that we can handle case 2

Thanks & regards,

Prashant Rane
