Syntax error when executing a process chain.

Question

Hi gurus,
This is a weird problem that we have been facing since yesterday. In the transaction RSPC, we had created a process chain in Feb 09. It ran smoothly till yesterday. However when I try to schedule the process chain now, it gives me a dump stating  Syntax error in program "CL_RSDMD_IOBJ_U_TPL===========CP ".
This same dump is generated whenever I try to display variant of one of the nodes of Process Chain.
I tried checking the corresponding programs but in vain. I have no Idea why am I receiving the error.
If anyone has faced this problem please post the same.
The following is brief overview of the dump.
Information on where terminated Termination occurred in the ABAP program
"CL_RSBK_DTP_DATABASE==========CP" - in "COPY_FROM_DB". The main program was
"RSPC_MAINTAIN ". 
In the source code you have the termination point in line 166
of the (Include) program "CL_RSBK_DTP_DATABASE==========CM003".
Any help would be appreciated.
Regards,
Sree.

Hi Rayapa,
There is no Long text as such, however, there is a short text which I have mentioned in my question itself.
And there is a What Happened
which is as follows
Error in the ABAP Application Program
The current ABAP program "CL_RSBK_DTP_DATABASE==========CP" had to be
terminated because it has
come across a statement that unfortunately cannot be executed.
The following syntax error occurred in program
"CL_RSDMD_IOBJ_U_TPL===========CP " in include
"CL_RSDMD_IOBJ_U_TPL===========CM00E " in
line 4:
"Field "P_BOOKMODE" is unknown. It is neither in one of the specified t"
"ables nor defined by a "DATA" statement. "DATA" statement."
The include has been created and last changed by:
Created by: "SAP"
Last changed by: "<My SAP user>"
