Doubts regarding BAPI

[Former Member]

Hi,

1) Can we use both Tables and Changing parameters while creating Function modules and BAPI? Please tell the difference b/w Tables and Changing?

2) Is it mandatory that we should pass internal tables with out header line through FM and BAPI?

3) Is it mandatory that Parameters that we pass should be "pass by value"?

Thanks in advance...

Hi

1) Yes. A table parameter is by definition a structured multi line parameter, a changing parameter is a single line (or value) fulfilling the requirement of both import and export parameters.

2) No. You may pass an itab with a header line.

3) See the help for each parameter type:

You pass the parameter with values. This means that the parameter contents are copied both when the parameter is passed and when it is transferred back to the calling parameter. For structures that contain tables, performance may be reduced considerably. Therefore, you should not do this.

hi,

check this link

1. we can use both changing and tables parameters.. if itr is required.

tables parameters is for passing tables

changing is for passing the variables with pass by value.

3. when you pass the values with import and export parameters.. by default it is passed by referance.. whereas changing is used for passing by value..

tables are always passed by referance.
