Enter valid Sign

Hello Experts,

we have the problem that the customer can not enter negative values into a table in PaPM. (Gültiges Vorzeichen eingeben = Enter valid sign). We can do it but he cant. The field is a normal Decimal field (17,2). Has a similar thing already occured at some of your projects ?

Best regards and thanks in advance, Philipp

Dear Philip,

I understand that you got an error message Gültiges Vorzeichen eingeben/Enter a valid sign“ when trying to maintain negative values into a table in PaPM.

Please be advised that maintaining negative values or entries with a negative “-” sign in a Model Table with source: Environment is not automatically accepted by PaPM and will encounter a warning message like you encountered in the screenshot you provided.

In order to resolve the issue, kindly perform the provided steps below:

1. Launched transaction code SE38

2. In the program field, key in “/NXI/P1_FW_ENVF_ACT”

3. Choose Execute

4. In the Enable sign/lowercase for environment fields screen indicate the following:



Note: Checkbox for Master Data/Hier Views should be selected if there are environment fields with master data being used

5. Choose Execute once more. A message log like the one below will then be displayed indicating a successful execution

6. Go back to the environment and re-activate the Model Table function.

Could you please try on your end and let us know how it works for you?

Kind Regards,

Big thanks for your response and detailed description!

We found out why it didnt work: There were missing Data elements in the respective table-> when we activated the table, there were no data created, so PaPM didnt know which values it could accept.

Again, thank you very much for your quick response
