Function Module move_char_to_num

[Former Member]

This is part of a program to trace changes done to Credit Limit. Value_new and Value_old fields are characters. I want to convert this to numeric. The following code is not working. Without the function module it is working fine. Kindly help.

SELECT OBJECTCLAS

AND FNAME IN S_FNAME AND

FNAME = 'KLIMG' OR

hi,

Are you sure that WA_CDPOS-VALUE_NEW contains only numbers? pls. add the following line before the FM call:

CHECK WA_CDPOS-VALUE_NEW CO '0123456789'.

On the other hand the type of WA_CDPOS-VALNEW has to be P.

hope this helps
