BAPI_PROJECT_MAINTAIN - problems when updating project's dates

mario_maisto — Mon, 15 Aug 2016 14:26:58 GMT

Hey there!

I was wondering maybe someone could help me with an issue when trying to update project information (i.e updating dates).
For doing that, I am using the BAPI BAPI_PROJECT_MAINTAIN.

For example, when trying to update the start and end date of a wbs element, I am populating these rows in the bapi's tables:

I_PROJECT_DEFINITION and I_PROJECT_DEFINITION _UPD (insert the project definiton and the corresponding X in the update table)
I_WBS_ELEMENT_TABLE and I_WBS_ELEMENT_TABLE_UPD
- with data of:

and

I_METHOD_PROJECT
- with data of:

But, the E_MESSAGE_TABLE returns me an error alongside with some warning and information messages, like:

Error: "Field /Time Stamp: Changing the contents of the field is not permitted"

Information: "TTR_INIT"

However, when I go to the Project Builder (cj20n), I can see that the dates have been successfully updated.. Still - the returned error message concerns me - does anyone have any explanation for these errors and knows how to resolve this?

Thank you ,
Mario

Hi Mario,

you can use below BAPI in sequence.

BAPI_PS_INITIALIZATION

BAPI_BUS2054_CHANGE_MULTI

BAPI_PS_PRECOMMIT

BAPI_TRANSACTION_COMMIT

Please read the FM Documentation.

Hello,

thank you for your answer - I tried your solution, and when trying to change the dates with BAPI_BUS2054_CHANGE_MULTI, I get an error of "Enter an allowed object class.".

The code I tried it with is as follows:


I_PROJ = 'Z/003'
WA_IT_WBS_ELEMENT-WBS_ELEMENT = 'Z/003-12'.
 WA_IT_WBS_ELEMENT-WBS_BASIC_START_DATE = '20160803'.
 WA_IT_WBS_ELEMENT-WBS_BASIC_FINISH_DATE = '20160826'.
 APPEND WA_IT_WBS_ELEMENT TO IT_WBS_ELEMENT.
 WA_IT_UPDATE_WBS_ELEMENT-WBS_ELEMENT = 'Z/003-12'.
 WA_IT_UPDATE_WBS_ELEMENT-WBS_BASIC_FINISH_DATE = 'X'.
 WA_IT_UPDATE_WBS_ELEMENT-WBS_BASIC_FINISH_DATE = 'X'.
 APPEND WA_IT_UPDATE_WBS_ELEMENT TO IT_UPDATE_WBS_ELEMENT.
 
 CALL FUNCTION 'BAPI_PS_INITIALIZATION'
             .
 
   CALL FUNCTION 'BAPI_BUS2054_CHANGE_MULTI'
    EXPORTING
      I_PROJECT_DEFINITION        = I_PROJ
    TABLES
      IT_WBS_ELEMENT              = IT_WBS_ELEMENT
      IT_UPDATE_WBS_ELEMENT       = IT_UPDATE_WBS_ELEMENT
     ET_RETURN                   = ET_RETURN    <<<<<<<< RETURNS THE ERROR MESSAGE
 **     EXTENSIONIN                 =
 **     EXTENSIONOUT                =
 *            .
  CALL FUNCTION 'BAPI_PS_PRECOMMIT'
   TABLES
     ET_RETURN       = ET_RETURN
 *            .
  CALL FUNCTION 'BAPI_TRANSACTION_COMMIT'
 **   EXPORTING
 **     WAIT          =
   IMPORTING
      RETURN        = ET_RETURN

Still - I think the same thing could also be done in the BAPI_PROJECT_MAINTAIN, as it supports changing the milestones and network as well (also need to change those too). Furthermore - I get the same error "Field /Time Stamp: Changing the contents of the field is not permitted" when trying to update the wbs description, but when checking the project with cj20n I can see that the description has been actually changed successfully.

Heres a snapshot of the returned messages when trying to update the dates/description with BAPI_PROJECT_MAINTAIN:

Any ideas what i am doing wrong?

hi mario,

i think you have missed some parameters in the above function module,


data : ls_extensionin TYPE bapiparex,
          lt_extensionin TYPE STANDARD TABLE OF bapiparex.


CLEAR ls_extensionin.

ls_extensionin-structure = 'BAPI_TE_WBS_ELEMENT'.   " Extension Structure


ls_extensionin-valuepart1 = ls_te_wbs_element.

APPEND ls_extensionin TO lt_extensionin.


pass this  lt_extensionin to extensionin(parameter) of above FM...

regards,

vinay....

Hello Vinay,
thanks for you answer! I ran into some similar problems with your suggested BAPI.. Nevertheless - my primary wish was to use the BAPI_PROJECT_MAINTAIN, as is should allow me to change every project detail. I followed the BAPI's documentation and used the exact same fields as was in the sample of the documentation - still I get the error message.
