Narrative:
DC9 aircraft arrived at gate with following write-up. Computer flag, first officer ADI. Found first officer steering computer missing from rack. Checked aircraft compartment to locate missing part. Could not be found. Installed svcable part, operations checked normal. After this event, I found out aircraft had been in heavy maintenance and flown 1 leg. Upon discussion with tech center, I found out the serial number of the part that was supposed to be in the aircraft. After talking with tech center. I used this serial number on aircraft log sheet to make it easier to enter into direct data entry on company computer system. Please note I had no intention of dispatching the aircraft with this part missing. My mistake was using the serial number of the part that was supposed to be in the aircraft on the log sheet. I'm so used to writing 'removed and replaced' in the log sheet sign-offs that it trapped me. Thinking back, I should have slowed down and assessed the situation. The proper way to do it would be to just install the part only and leave the off serial number block on log sheet blank.
