Please note that GST settings should not be utilized at this time. To rectify this:
Go to Housekeeping, Setup, General Setup, Company Profile, Un-Tick with Malaysia GST.
Exit the setup.
Go to Housekeeping, Setup, General Setup, Transactions, Tick Select Tax code from tax code maintenance.
Note: This action will eliminate the message you encountered, as it pertains to the GST format. Please be aware that we no longer actively develop this aspect of the program. However, it will remain in the system, as there is a possibility that the government may consider reintroducing the GST system in the future, and we have opted not to remove it at this time.
