Former Member — Tue, 08 Dec 2009 08:20:33 GMT

while using the code.

*select * from mara into table it_mara*

where matnr between p_matnr_low and p_matnr_high.

endmethod.

error generated : "IT_MARA" is not an internal table - the "OCCURS n" specification is missing

although i hav declared it_mara in parameter section while creating interface.

Kindly Suggest.

How did you define the parameter, you should define it TYPE Zxxx where Zxxx is an internal table (with OCCURS clause), else this is a single field/structure. Define your own or use a type-pools or a table type like EXPO_MARA_T.

you have to declare your parameter as reference to a table type. Pls declare it_mara TYPE MARA_TT where MARA_TT is a table type.

Hi!

Create a tabletype in SE11.

Choose datatype radiobutton, give the name, like ZZMARA and click create.

Choose the tabletype from the popup and enter

Give MARA to the type of the line.

Save and activate it.

And of course use it in your method's parameters.

First of all, read the ABAP help, and SAP Help, specifically about "table types".

In this context mara is NOT a table type. It is a structure. As everyone has so far suggested: use a table type. You have a few choices

1. Define an appropriate table type in your class

2. Define an appropriate table type in the data dictionary

3. Use an appropriate table type already defined in the data dictionary

4. Define it_mara in the method, as being TYPE STANDARD TABLE, and define its actual type in the calling program.
