I want to edit some transaction master data from Backend but when I edit I get this error but if I use ADMIN to edit I have no issue.
The value of column LastModifiedUserID in table POS does not exist in its master file.
Possible Reason :
This is because Backend user and Frontend user are not the same. POS not able to detect the Accounting User ID.
If you want to edit master data other than using ADMIN ID, you have to create the same Backend user ID at Frontend POS User.
1. Login POS 5.0 Backend > Point of Sale > Maintenance > POS User Maintenance > New
2. Fill in the user ID which are identical to your Backend user ID > OK
3. Go back POS Transaction Viewer edit & save again
