Table T511 Wage Types - KOMBI Field Value Wrong

Hello,

We are having an issue with Membership Fees IT0057 whereby even though we have set in screen control the field for the actualy fee to be OF Optional Field, for South Korea we are getting an error message saying it is mandatory.

This only happends for South Korea, nor our 24 other locations.

I have tracked this down to table T511 field KOMBI (combination check).

All our other country enries have '9' Amount optional, no number/unit however for South Korea MOLGA 41 this value is set to '1' Amount required, no number/unit.

I cannot find anywhere in SPRO how to change this value.

Can anyone tells me how I can change this value?

Many Thanks

David
