How To Fix VH601 - Number (condtion x access sequence) without prestep

VH601 - Overview

• Message type: E = Error

• Message class: VH - SD pricing

• Message number: 601

• Message text: Number (condtion x access sequence) without prestep

Using the presteps
There are access to condition tables in your system that can be
optimized.

How to fix this error?

Activate access optimization if possible.
Rule of thumb for using the optimization option
Reading the condition tables is only possible in a small percentage of
cases (e.g. the condition table has few entries). The gain in
performance is much greater, the more often the access is successful
(e.g. the access is near the beginning of the access sequence).
Warning
If you expect the generic access (only header fields filled) of the
condition table to be successful, then you should not use the
optimization option because it could have an adverse effect on
performance.

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

• What is the cause and solution for SAP error message VH601 - Number (condtion x access sequence) without prestep ?

  SAP Error Message:
  VH601 Number (condition x access sequence) without prestep
  
  Cause
  This error typically occurs in the SAP Pricing procedure when a condition type is assigned to an access sequence that does not have a defined "prestep" or prerequisite condition. In other words, the system expects a certain condition or step to be processed before the current condition, but it is missing or not properly configured.
  More specifically:
  
  The access sequence assigned to the condition type requires a "prestep" condition to determine the number or value to be used in the condition record.
  If the access sequence or condition type configuration lacks this prestep, the system cannot correctly determine the condition record, leading to this error.
  This often happens when customizing pricing procedures or condition types, especially when using number ranges or condition records that depend on a previous condition.
  
  
  Solution
  
  
  Check the Access Sequence Configuration:
  
  Go to transaction V/07 (Maintain Access Sequences).
  Verify the access sequence assigned to the
