How To Fix TW704 - Table cache is too small for view &1, increase the value

SAP Error Message - Details

• Message type: E = Error

• Message class: TW - R3trans - Messages

• Message number: 704

• Message text: Table cache is too small for view &1, increase the value

What causes this issue?

To import view contents, it is necessary to compare the database
contents of the transported key area with the data to be imported. This
comparison can only take place in the main memory of R3trans.
In this case, the memory area available was too small.

System Response

The system cancels the import of view contents.

How to fix this error?

If possible, you should increase the size of the memory area available
to R3trans for mixing table contents.
First check the current value of this parameter. It is specified at the
beginning of the log. The parameter is called "table cache" in the log.
There are three possible cases:

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

<ZH>You specified "dynamic" for the value</>
This means that R3trans continues to request additional memory from the
operating system until the operating system has no more memory to
provide.
In this case, you must try to increase the parameters of the operating
system and its resources.
<ZH>You specified a number for the value, your operating system is not
AS400</>
In this case, you can raise the number. Your operating system does not
support the dynamic memory request used by R3trans. The memory limit
was not reached with the current value. You can change the parameter
with the R3trans parameter "table_cache_size" of "tcs". You can pass
R3trans parameters to R3trans via the tp parameter "r3transoptions" of
tp. Example: To raise the value from 16000000 to 32000000, insert the
following line in your transport profile (TPPARAM):
<SID>/r3transoptions = tcs=32000000
<ZH>You specified a number for the value, your operating system is
AS400</>
On AS400 there are only 16000000 addressable bytes per piece. You must
not and cannot exceed this value. Transport smaller key areas of your
view data.

• What is the cause and solution for SAP error message TW704 - Table cache is too small for view &1, increase the value ?

  The SAP error message TW704 indicates that the table cache is too small for a specific view, which can lead to performance issues or the inability to access certain data. This error typically arises when the system is trying to access a view that requires more memory than is currently allocated in the table cache.
  Cause:
  
  Insufficient Cache Size: The default size of the table cache is not sufficient to handle the data being accessed, especially if the view is complex or involves a large amount of data.
  High Data Volume: If the application is dealing with a large volume of data or if there are many concurrent users accessing the same view, the cache may become overwhelmed.
  Configuration Issues: The system may not be optimally configured for the specific workload or data access patterns.
  
  Solution:
  To resolve the TW704 error, you can increase the size of the table cache. Here are the steps to do this:
  
  Access the SAP GUI: Log in to your SAP system.
  Transaction Code: Use transaction code RZ10 to access the profile parameters.
  Edit Profile Parameters:
  
  Look for the parameter abap/heap_area_total.
  Increase the value of this parameter to allocate more memory for the table cache.
  You may also want to check the parameter abap/heap_area_dia for dialog processes.
  
  
  Save Changes: After making the changes, save the profile.
  Restart the System: For the changes to take effect, you may need to restart the SAP application server.
  
  Related Information:
  
  Monitoring: Use transaction ST02 (Tune Summary) to monitor the buffer and cache usage. This can help you identify if the cache is indeed the issue and how much memory is being used.
  Performance Tuning: Regularly monitor and tune your SAP system's performance, especially if you notice frequent cache-related errors.
  Documentation: Refer to SAP Notes and documentation for specific recommendations on cache sizes based on your system's configuration and workload.
  Consult Basis Team: If you are unsure about making these changes, consult your SAP Basis team or system administrator for assistance.
  
  By increasing the table cache size, you should be able to resolve the TW704 error and improve the performance of your SAP system when accessing the affected view.
