Selection-screen: Input help for VTWEG

Former Member — Thu, 08 Jun 2006 13:35:27 GMT

Hello!

Can anybody help me with the following problem:

I have two select-options (VKORG and VTWEG) on my selection screen. Now there should be the possibility to restrict the values shown as input help for VTWEG after having selected a value for VKORG.

I've already tried to do this by using a matchcode object but for VKORG and VTWEG I was not able to find suitable search helps.

In my opinion this should be possible without using the "AT SELECTION-SCREEN ON VALUE-REQUEST FOR ...". If not, it would be interesting to getting to know your approaches to this task.

Thank you in advance!

you can refer to the following code

and you can write the code in the same way as per your requirement

how did u ever know that VKORG was selected? VGWEG is dependent on VKORG based on the configuration data on that sitew, so, use parameer id's in assosiation with your paramerer id's.

Hi, if you can't get it to work any other way, you can try this.



report zrich_0002 .

parameters: p_vkorg type vbak-vkorg,
            p_vtweg type vbak-vtweg.

  data: dynfields type table of dynpread with header line.


  dynfields-fieldname = 'P_VKORG'.
  append dynfields.

  call function 'DYNP_VALUES_READ'
       exporting

You should use of fm 'DYNP_VALUES_READ' to read the values on selection screen in at selection screen of second field. Then you can check and restrict the user.

You don't have to do any special coding, I've seen this work in 4.6c and 5.0.

Try the following code:

tables vbak.

select-options: s_vkorg for vbak-vkorg,

s_vtweg for vbak-vtweg.

start-of-selection.

....

Once you select a value for vkorg, vtweg match code automatically shows distribution channels for the selected sales org.

Interesting, works for SELECT-OPTIONS, but not for PARAMETERS.

report zrich_0001 .

tables vbak.
select-options: s_vkorg for vbak-vkorg,
s_vtweg for vbak-vtweg.

parameters: p_vkorg type vbak-vkorg,
            p_vtweg type vbak-vtweg.


start-of-selection.

Thank you Sridhar, that solved the problem!

A further question regarding this topic:

I've selected a VKORG and a VTWEG. On the selection screen there is another input field to select one or more materials.

Is it possible to restrict the selectable materials to only those, which are maintained for the selected VKORG and VTWEG? Perhaps as easy as the first solution?

Thank you in advance!

HI empe,

1. Is it possible to restrict the selectable materials to only those, which are maintained for the selected VKORG and VTWEG?

Yes its possible thru

search help (either standard or our own)

2. The search help should contain

all these 3 fields.

a) then we can use IMPORT checkbox

(when we make search help)

for the fields

VKORG and VTWEG

b) so that, when we press F4 for material,

only those material will come

which are related to the values entered

in the fields

VKORG and VTWEG

(this is made done by making them IMPORT

checkbox tick, while making search help,

-- that is the main purpose of it)

regards,

amit m.

You can do it easly by a dictionary structure.

By SE11 create a structure ZMVKE like this:

FIELD| DATA ELEMENT| CHECK TABLE| SEARCH HELP

VKORG| VKORG | TVKO |

VTWEG| VTWEG | TVKOV |

MATNR| MATNR | MVKE | MAT1S

So use this structure to define yuor select-options:
