Add FIELDS (NO MSEG or MKBF) TO Layout MB51

[Former Member]

Hello Guys,

I saw a lot of discussions concerning this issue.
But no one helped me out.

I have to add 2 fields MAterial belonging to ORDER and the description of this material (MAKT)

I see everywhere you have to use Enhancement Spot ES_RM07DOCS.
Buit when  i look in program RM07DOCS i see many of these spots..

\PR:RM07DOCS\EX:RM07DOCS_01	Dynamic Enhancement Point		Event	AT SELECTION-SCREEN
\PR:RM07DOCS\EX:RM07DOCS_02	Static Enhancement Point		Before First Unit	N->RM07DOCS
\PR:RM07DOCS\EX:RM07DOCS_03	Static Enhancement Point		Before First Unit	N->RM07DOCS
\PR:RM07DOCS\EX:RM07DOCS_04	Dynamic Enhancement Point		Event	INITIALIZATION
\PR:RM07DOCS\EX:RM07DOCS_05	Dynamic Enhancement Point		Event	AT SELECTION-SCREEN OUTPUT
\PR:RM07DOCS\EX:RM07DOCS_06	Dynamic Enhancement Section		Subroutine	PROCESS_LIST
\PR:RM07DOCS\EX:RM07DOCS_07	Dynamic Enhancement Point		Subroutine	BUILD_FIELDCATALOG
\PR:RM07DOCS\EX:RM07DOCS_08	Static Enhancement Point		Before First Unit	N->RM07DOCS

\PR:RM07DOCS\EX:RM07DOCS_11	Dynamic Enhancement Section		Subroutine	PROCESS_LIST
\PR:RM07DOCS\EX:RM07DOCS_O1	Dynamic Enhancement Point		Event	INITIALIZATION
\PR:RM07DOCS\EX:RM07DOCS_G4	Static Enhancement Point		Before First Unit	N->RM07DOCS
\PR:RM07DOCS\EX:RM07DOCS_G5	Dynamic Enhancement Point		Before First Unit	N->RM07DOCS
\PR:RM07DOCS\EX:RM07DOCS_G6	Static Enhancement Point		Before First Unit	N->RM07DOCS
\PR:RM07DOCS\EX:RM07DOCS_G7	Dynamic Enhancement Point		Before First Unit	N->RM07DOCS

Could someone explain me clearly which steps i have to perform to get these 2 fields filled in the layout of MB51

Thanx in advance.

Hi Frank

Please, see SAP Note 357187 - MB51: Fields in field catalog / selection screen.

I hope this helps you

Hi Eduardo,

I saw you have given this oss-note in more discussions about this.
But this issue is only about mseg and mkbf lfields not over fields form oter tables.

Using implicit enhancements you can add fields to the structure ITAB and populate the fields in form DATA_SELECTION.  Both are in include RM07DOCS_GENERATED.

[Former Member]

how are you able to add fields to ITAB?

You can create a table using

CALL METHOD cl_alv_table_create=>create_dynamic_table

but you still cannot modify ITAB and add entries to them using enhancemts or field symbols.

In other words, SAP doesn't allow you modify internal tables created during runtime...

please me know.

thanks

Implicit enhancements will allow you to add fields to any declared structure.  My code looks like this:

...
data: XBLNR type MKPF-XBLNR .
data: ZEILE type MSEG-ZEILE .
ENHANCEMENT 7  Z_MB51_ENH.    "active version
 INCLUDE type z_mb51_enhanced=>extra_fields.
 ENDENHANCEMENT.
data: end of itab.
