Hi

You can use the nested structures in RFC/any fun module creation depending on your requirement.

see the doc on Deep/Nested Internal tables/structures

structures containing internal tables as components or

Internal table containing Structure as components are called Deep Internal table.

Please check this link for reading a deep structure.

Example:

TYPES: BEGIN OF TYPE_DEEP,

MATNR TYPE MATNR,

T_MARC TYPE MARC OCCURS 0,

END OF TYPE_DEEP.

DATA: T_DEEP TYPE STANDARD TABLE OF TYPE_DEEP.

DATA: WA_DEEP TYPE TYPE_DEEP.

DATA: T_MARC TYPE TABLE OF MARC.

DATA: S_MARC TYPE MARC.

• Populating data.

WA_DEEP-MATNR = 'TEST'.

S_MARC-MATNR = 'TEST'.

S_MARC-WERKS = '9090'.

APPEND S_MARC TO T_MARC.

• Append second level internal table.

WA_DEEP-T_MARC[] = T_MARC[].

• Append.

APPEND WA_DEEP TO T_DEEP.

• Process the internal table.

LOOP AT T_DEEP INTO WA_DEEP.

WRITE: / WA_DEEP-MATNR.

• PROCESS the second level internal table.

LOOP AT WA_DEEP-T_MARC INTO S_MARC.

WRITE: S_MARC-WERKS.

ENDLOOP.

ENDLOOP.
