I want to create a mapping like the ABAP function:
CONVERSION_EXIT_MATN1_INPUT
for example:
1 => 000000000000000001(add zeros if input value is
numeric)
Z => Z(no change if input is not numeric)
The standard function "formatnum" works well from 1 => 000000000000000001.But it causes a java exception from Z => Z.
How to solve it?
Must i develop a UDF?
thanks
