You can use BD87 if you want to reprocess same idoc

number,here it will not generate new idoc number.

suppose there was RFC Issue ,connection got failed then

after rectifying RFC Connection then you can reprocess

same idoc number.

in case data is missing,then you need to WE19 Transaction -

> enter idoc number -> fill the missing data.

just drag the segments ,here you can fill data where ever

required.

If you use WE19 then it creates new idoc ,it gives work

flow message.
