Check the Current India Localization Patchset level installed on an Instance
India Localization mainly acts based on the Descriptive Flexfields (DFF's)
The DFF's attribute 1 to 5, 14 and 15 will be used by India Localization patch. If we have any data in that field we have to move it manually and check whether the data's were moved safe to other fields and then we can apply the patch. If we have not moved the data's from the appropriate field and if we apply India Localization Patch it will delete all the data in the fields 1 to 5, 14 and 15 and will use for India Localization.
This check is mandatory since India Localization patchset installation scripts will delete any previous registrations of attributes 1 to 5, 14 and 15 with Global Data Elements in the DFF's (AP_INVOICES, AP_INVOICE_DISTRIBUTION, FA_ADDITIONS, FA_MASS_ADDITIONS, FND_COMMON_LOOKUPS, MTL_SYSTEM_ITEMS, PER_ORGANIZATION, RCV_SHIPMENT_HEADERS, PO_LOOKUP_CODES)
