How To Fix 28135 - Dependency cannot be compiled: reason #&1

SAP Error Message - Details

• Message type: E = Error

• Message class: 28 - Configuration

• Message number: 135

• Message text: Dependency cannot be compiled: reason #&1

What causes this issue?

The system found an error (#&V1&) when generating intermediate code for
the dependency.
#1 - Compilation too long
Probable cause: The dependency is transformed internally to
"disjunctive normal form" as shown in the following example:
(a OR b) AND (c OR d) becomes
(a AND c) OR (a AND d) OR (b AND c) OR (b AND d)
In dependencies where many parenthical expressions are linked with an
AND operation, and these parenthetical expressions have sub-expressions
that are linked with an OR operation, the disjunctive normal form of
object dependencies can be very long. This is why a maximum length has
been defined. The current dependency exceeds this length.

System Response

The system marks the dependency as incorrect. This means that it cannot
be released for operative use.

How to fix this error?

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

#1 - Compilation too long:
Try to avoid OR in inner parenthetical expressions. For example:
COLOR = 'red' OR COLOR = 'blue'
instead of
COLOR IN ['red', 'blue']

• What is the cause and solution for SAP error message 28135 - Dependency cannot be compiled: reason #&1 ?

  The SAP error message 28135, "Dependency cannot be compiled: reason #&1," typically indicates that there is an issue with the dependencies of a particular object in the SAP system. This error can occur in various contexts, such as when working with ABAP programs, function modules, or other development objects.
  Causes:
  
  Missing Dependencies: The object you are trying to compile may depend on other objects (like classes, function modules, or data elements) that are either missing or not activated.
  Inconsistent State: The object might be in an inconsistent state due to changes made to its dependencies that have not been activated or compiled.
  Syntax Errors: There may be syntax errors in the code that prevent successful compilation.
  Transport Issues: If the object was transported from another system, there may be missing dependencies that were not included in the transport request.
  Version Conflicts: There may be version conflicts between the object and its dependencies, especially if multiple developers are working on the same objects.
  
  Solutions:
  
  Check Dependencies: Review the dependencies of the object in the Object Navigator (SE80) or the ABAP Workbench (SE38). Ensure that all required objects are available and activated.
  Activate Objects: If you find any inactive objects that the current object depends on, activate them first.
  Syntax Check: Perform a syntax check on the object (using the "Check" button in the ABAP editor) to identify any syntax errors that need to be resolved.
  Transport Request: If the object was transported, ensure that all related objects were included in the transport request and are available in the target system.
  Recompile: After resolving any issues, try recompiling the object to see if the error persists.
  Check for Locks: Ensure that the object is not locked by another user or process, which could prevent compilation.
  
  Related Information:
  
  Transaction Codes: Use transaction codes like SE80 (Object Navigator), SE38 (ABAP Editor), or SE11 (Data Dictionary) to investigate and manage your objects.
  SAP Notes: Check the SAP Support Portal for any relevant SAP Notes that might address specific issues related to this error message.
  Debugging: If the issue persists, consider using debugging tools to trace the compilation process and identify the root cause.
