Substitution Exit for AR01

Question

Hey All,
      I have a requirement in which I want to run the AR01 report for asset balances based on customer number ( Custom Z Field saved in the ANLU table ). The current selection criteria does not have the customer number. Can this be done be not creating a custom report and by using some exits or substitution rules. Say for example Can I create a substitution exit to copy the customer field to the Asset super number field (which is currently in the selection criteria) . The substitution Field to Field doesnt help as the table ANLU is not avalaible for substitution. What options do i have in this case.
Any suggestion is highly appreciated.
Thanks,
Aparna.

hi aparna,
Validation Rules  and Substitution User exits
Syntax:
=Uzzzz (zzzz = up to 4 characters - this is true for Document Level validations - call point 3 - *Header Level & Line Item Level - call points 1 & 2 - allow up to 30 charaters.)
/NORFB->Bus.transactions->Base parameters->Validation
/NORFB->Bus.transactions->Base parameters->Substitution
Example
=ULTE "FI_DOCU 001 "Parked SA,FY,SI=>long text CORRESP. "
=U&VALID_WBS_IN_ZUONR "FI_ITEM 011 Spon.Res: Check WBS valid in ZUONR"
changed in 4.5B (* Form UFIA -- formerly U&VALID_WBS_IN_ZUONR)
User exits are form routines that the user programs. There are two types of user-exits:
1. Validation exits are used in the prerequisites and checks. They have either the value 'T' for true or 'F' for false. They are interpreted as a part of the logical statement, like a constant or field comparison. For this type of user exit, you must fill a parameter with the results of your check ('T' for true; 'F' for false).
Example
FORM Uzzzz USING B_RESULT. "'T' or 'F'
from program ZGGBR000 (ZGGBRI03)
2. Substitution exits are used to change one or more fields. However, you can only change those fields that are permitted in the Boolean class for the substitution. You can display these fields by selecting the following menu options in substitution maintenance: <Extras -> Fields for substitutions>
Example
FORM Uzzzz USING COST_CENTER.
from program ZGGBS000 (ZGGBSI02)
Substitution Fields can be found from this window
/NORFB->Bus.transactions->Base parameters->Substitution->Call Pnt 2->Substitution step 3->Extras->Substitution flds
The name of the form pool (e.g., ZGGBR000 & ZGGBS000) that contains your user exit must be stored in table T80D.
Note
1. Data declaration
Tables and field stings cannot be declared in form routines, so that the contents can be used along with the calling transaction.
2. Parameter definition
It is important that you make declare the code generation program for your user exit; how many and what type of parameters you are using for the user exit. You do this by entering your newly defined user exits in the form routine GET_EXIT_TITLES.
found in program ZGGBR000 (ZGGBRTIT)
found in program ZGGBS000 (ZGGBSTIT)
One exception is the parameter for the results of a validation exit. You must not declare this, it is automatically generated be the system. What types of parameters are available and how you use them is described in the online documentation. When creating your user exits, you can use the example form pools delivered by SAP (RGGBR000 for validations; RGBBS000 for substitutions) as a reference. We recommend that you copy the example form pools delivered by SAP when creating your own user exits. In these example form pools, entries already exist in the form routine GET_EXIT_TITLES for the examples delivered. The GET_EXIT_TITLES must absolutely exist in your form pool. 
You can find additional information on the creation of user exits in the online documentation on validations and substitutions.
SAP exits
SAP exits are form rountines programmed by SAP. The name of the form pool is SAPFGBEB.
Syntax:
=Szzzz (zzzz = up to four characters)
FORM Szzzz using B_result. "'T' or 'F'
Example
=S01 "SAP exit S01"
Display description of T80D configuration
Return ->
Change Validation: FI_ITEM (Message view)
