what are conversion routines

Hi,

Conversion routines are the routines which convert the data from external sap format to sap format and vice-versa.

For any field like sales order length is 10 characters.

If u enter sales order 3456, then it means u r entering 4 characters, it has to convert into 10 characters with 0s like 0000003456.

sap takes 3456 as 0000003456.

while displaying it converts from 0000003456 to 3456

for this we need conversions

Hi,

A conversion routine conv is represented by two function modules that adhere to the naming convention CONVERSION_EXIT_conv_INPUT|OUTPUT. In these function modules, no statements can be executed that interrupt the program flow or end a SAP LUW. A conversion routine can be assigned to a domain in the ABAP Dictionary. If a screen field refers to a domain with a conversion routine, the system automatically executes the function module ..._INPUT for every input in the relevant screen field and the function module ..._OUTPUT when values are displayed in this screen field and uses the converted content in each case. If a data object refers to such a domain, the function module ..._OUTPUT is executed for the output of the data object in a list and the converted content is displayed.
