How to define certain document type (BKPF-BLART) for certain movement (101)

Question

Sometimes ( I think it is becuase of the tcode)  certain purchase 101 movements create a WA type FI document and some other times purchase 101 movements create WE type FI documents. I have seen a table ( accessing from omba transaction) in which for diffenent tcode´s we have either WE or WA. If we always use migo transaction why sometimes in bkpf we have migo_tr, migo_gi, ....;....
How should I do in order to create always WE FI documents for purchase 101 movements?
Thanks in advance.

Answer 1

Check the settings in SPRO-MM-Inventory Management-Number assignemnt-Define number ranges for accounting documents.
Here you assign accounting document type to tcodes.
Normally , WA is used in receipts for MB1C/MIGO_GI tcode - for e.g for 561 mvmt type.
SAP recomends keeping this setting as it is.
SAP help text copied here for reference:
Define Number Assignment for Accounting Documents
In this step, you set the number ranges for the accounting documents which are created when goods movements or inventory differences are posted.
Accounting documents in inventory management
For accounting-relevant goods movements, the system creates two different documents:
material document
accounting document
Both the material documents and the accounting documents have their own document numbers. When inventory differences are posted, the system also creates an accounting document for the physical inventory document.
In this step, you only maintain the number assignment for accounting documents.
Document types
Accounting documents are split into document types to allow differentiated document number assignment, which is the basis for distinguishing between the various accounting operations. A number range is assigned to each document type. In a company code, you have to define number intervals for each number range and fiscal year.
In inventory management, the transaction determines which document type is used.
Example: Goods receipt for purchase order
Requirements
You have already defined the company code.
Default Settings
In the standard SAP System, the following document types are predefined for inventory management:
WA  for goods issues, transfer postings, other goods receipts
WE  for goods receipts with reference to purchase orders
WF  for goods receipts with reference to production orders
WI  for inventory differences
WL  for goods issues with reference to deliveries (SD)
WN  for net posting of goods receipts
PR  for revaluation documents
Each document type is already assigned a number range. In company code 0001, number intervals are defined for each number range both for the current and the previous fiscal year.
Number range 49 with the year-related interval 4900000000 to 4999999999 is assigned to the document types for all goods movements, except goods movements with reference to purchase/production orders.
Document type WE is used for goods receipts with reference to purchase orders and production orders. This document type is assigned number range 50 with the year-related interval 5000000000 to 5099999999.
Please note that net postings of goods receipts (document type WN) are not active in the standard SAP System. If you want to post goods receipts net, you have to assign document type WN (instead of WE) to the transaction MB01.
Document type WI is used for posting inventory differences. This document type is assigned the number range 01 with the year-related interval 0100000000 to 019999999999.
SAP Recommendation
Activities
1. Check whether you can use the standard settings.
2. If not, you have to add new document types to satisfy your requirements:
a) Define a new document type under Financial accounting document
b) types.
c) Assign a number range to the document type.
d) Under Financial accounting number ranges, define the year-related number intervals for the given number range in your company code. If you do not want to use the year-related number assignment method, enter 9999 in the Year field.
e) Under Allocate document type to transaction, assign the relevant document type to the transaction codes of inventory management.
Document type PR (revaluation documents) is already assigned.
Notes on transport
You transport number range objects as follows:
Choose Interval -> Transport in the accounting document Number Range screen.
All intervals for the selected number range object are deleted in the target system first. After the import, only the intervals you export are present. The number statuses are imported with their values at the time of export.
Dependent tables are not transported or converted.
All other activities are linked to the automatic transport.
