negative values in table control

[former_member537489]

Dear experts, I use a DEC field in a table control, but when the user enters a negative value there, it gives an error : 'negative values not allowed'. What should I do in my screen so that to overcome this problem?

Thank you

Use a string or char type variable in the table control and then move that value entered in the table control into a Dec type variable in the module pool program.

So, should I use another format than DEC? I cannot see any format named VAR.

Hi Roxani,

You can use a data element or data type (CHAR) of length 18 directly.

In the PAI section, read the value entered on the table control into another variable of type CURR.

Hi Roxani!

Your dynpro just don't know where to put the sign. Define an edit mask in the attributes of the screen field '______V'(it's the field, where already the underline is in, delete the last underline and put V(orzeichen - german word for sign)).
