CONVERSION_EXIT_ALPHA_INPUT

[Former Member]

I created a new screen with one of the field like LIPS-VBELN, but when the Delivery number is entered, the leading zeroes are lost. Now I'm trying to use CONVERSION_EXIT_ALPHA_INPUT to force the screen display of the leading zeroes, but it does not work. Is there any setting of the screen field that I can check to get leading zeroes defaulted? Any other suggestions?

Hi,

Have you used the same data type(VBELN) to get the output from the FM CONVERSION_EXIT_ALPHA_INPUT.?

Input is char, output is numeric. The conversion works, but I think the problem is in the screen itself. I do not want to change the screen field to char, similar to standard SAP. I think it is not possible to retain the leading zeroes, because correlating SAP transactions also don't display the leading zeroes.

I'm not changing the type to e.g. type n as I don't want to work with any intermediate values. I'll simply justify it by referring to SAP standard display being exactly the same. Regards, Adrian

Hello Adrian,

SAP documentation on Conv. Exit says:

The function module ..._OUTPUT is automatically executed when values are displayed in this screen and the corresponding converted content is used.

So i guess you understand "why" the leading zeroes are vanishing ! Btw i'm not convinced why you need the leading zeroes anyway ?
