I am trying to change the table configuration in PM order service tab, some how the field Gross price and cost element fields are hidden in the service tab table. When I try to change the setting and try to activate it, However after saving the system variant system doesn't take the changes. It come back to the original setting.
I am following the below. Kindly let me know whether I am following the right step.
1) Click on table setting , 2) Click on administrator, 3) Select the field and do the necessary change to make visible or invisible, 4)Activate, 5)Close and 6) save.
I have also checked ML90 transaction for IW31, IW32 and the operation and PT9 (services), all places I found gross prices is optional.
Please let me know if i miss any thing here, what the other steps to make the field Gross price and cost element active in PM order service tab.
