Version field NOINPUT

Hi,
I have a VCH routine that makes a field (PRI.CUS.CARD.ID) as NOINPUT by using T(fld pos)<3> = "NOINPUT".
When the version is opened, I have a dropdown field and If I select a specific value ('P' : image below), I want to make PRI.CUS.CARD.ID as inputtable again.
I do T(fld pos)<3>= "" but the field is not shown on the screen as inputtable.
I also tried CALL REBUILD.SCREEN but it didn't work.
Note that I have T24 Desktop.

Also I noted this: I have many tabs (associated versions), and If a change tabs and come back to the first tab the field is shown now as inputtable.





Your advice please
Thanks

CALL REBUILD.SCREEN should do the job, works fine for me since years with desktop.
Are you sure CARD.TYPE has the actual value ? Do you move COMI to this field ??

I do this ...

1) On Field "CARD.TYPE" I have this VVR routine.

2) In routine ....
CARD.TYPE (variable) = COMI (Which now has value "P" as I selected from Version Input)

T (LT.CRD.ISS.PRI.CUS.CARD.ID)<3> = ""
CALL REBUILD.SCREEN

Rest of the flow that defaults some fields (R.NEW(...) = ...)

1) - Version is opened with the @ID “121212-0003”
- The first 2 fields are defaulted and made “NONINPUT” from VCH routine (Check record routine)



2) - A value is selected from dropdown field “Card Type”
- VVR HOT.FIELD routine that is attached on “Card Type” field is run that makes another field - “Primary Card Customer ID” as Input –
T(field pos)<3> =””, and then REBUILD.SCREEN is called.
The result is shown below (Field “Primary Card Customer ID”) remains as NOINPUT



I have noticed the following:
1. If I go to any other tab and come back to “Main”, the field “Primary Card Customer ID” is now shown as Inputtable (see image below).
2. If I press Commit (knowing that the record will not commit due to other validations), again the field “Primary Card Customer ID” is now
shown as Inputtable (see image below).



Any ideas on how to solve this problem?
Thanks
