IM_SYSTEM_OPTIONS_T table empty, no value for VAT_VALIDATION_TYPE

Hi all,

we are doing some testing on ReIM 13.2.8 version and we encountered a problem. We need to modify the column VAT_VALIDATION_TYPE to different values (R, I and S - different VAT types) but the table is empty, with no values. In the Data Model of ReIM, 13.2.4 version, there is on info about the column VAT_VALIDATION_TYPE nor the table IM_SYSTEM_OPTIONS_T. The table IM_SYSTEM_OPTIONS_T exists in the Data Model of ReIM, 14.1 version, but there is no information about the following table and column.

My question is, how can we populate the table, which data do we insert? With what objects is the table IM_SYSTEM_OPTIONS_T connected?
