Defendant was indicted for the offense of “attempted burglary” (criminal attempt to commit burglary). At trial, an eyewitness testified that on March 26, 1984, between midnight and 12:15 a.m. he saw *662defendant on the roof of Clary’s Drug Store “digging” at the roof with “a pole or a stick.” The witness further testified that before the police arrived, he observed defendant hide from a passing vehicle by “[ducking] down behind the duct work, the air conditioning work” on the roof of the drug store and, after the automobile had passed, defendant “looked and stood back up and resumed the digging motion.” The State introduced evidence that defendant had recently been released from prison after serving a sentence for burglarizing the same drug store. The State showed that defendant had burglarized the drug store in 1982 by gaining entry through the roof. From this evidence, defendant was found guilty of “attempted burglary.” The trial court denied defendant’s motion for new trial and this appeal followed. Held:
1. In his first enumeration of error defendant contends the trial court erred in allowing the State to introduce evidence of his prior conviction of burglary. “In order to introduce evidence of an independent offense as a relevant similar transaction the state must prove two factors. It must be shown that the defendant was in fact the perpetrator of the separate offense and that there is a sufficient similarity of offenses so that proof of the former tends to prove the latter. French v. State, 237 Ga. 620 (299 SE2d 410) (1976).” Moore v. State, 254 Ga. 674, 676 (333 SE2d 605). In the case sub judice, there is no question that defendant burglarized the same drug store and was convicted for this act in 1982. Further, in both incidents defendant went to the roof to gain entry to the store. Under these circumstances, we find sufficient similarity between the previous act and the crime charged to authorize introduction of the similar transaction evidence to show defendant’s motive in “digging” at the roof of Clary’s Drug Store in the early morning hours of March 26, 1984. See Millwood v. State, 164 Ga. App. 699 (1) (296 SE2d 239).
2. Next, defendant contends the evidence of his prior conviction should have been excluded at trial because the State failed to follow the pre-trial procedure prescribed by Uniform Superior Court Rules 31.1, 31.2 and 31.3 (253 Ga. 799, 853-854) for introducing such evidence at trial.
“The burden is on the party claiming error not only to show error, but error which injured him, and unless the error results in a miscarriage of justice or constitutes a substantial violation of a constitutional or statutory right, an appellate court will not reverse. Anderson v. State, 165 Ga. App. 885, 887 (3) (303 SE2d 57) (1983).” Stewart v. State, 180 Ga. App. 266, 267 (349 SE2d 18). In the case sub judice, a hearing was conducted prior to trial to determine the admissibility of the similar transaction evidence. During this hearing, defendant’s attorney stated that he “was put on notice some time ago by the District Attorney that she [intended] to . . . introduce evi*663dence of [defendant’s] prior convictions.” Further, as we held in Division 1 of this opinion, the trial court properly found the evidence of defendant’s prior conviction relevant and admissible at trial. Under these circumstances, while the record shows that the State erroneously failed to follow the procedure prescribed by the Uniform Rules for the Superior Court for introducing similar transaction evidence at trial, the defendant has shown no harm resulting from this omission. Consequently, this error does not require reversal of defendant’s conviction.
3. In his third and final enumeration of error defendant asserts the general grounds. This enumeration of error is without merit. The evidence presented at trial, construed most strongly to support the verdict, was more than sufficient to enable a rational trier of fact to find defendant guilty beyond a reasonable doubt of the offense charged. See Jackson v. Virginia, 443 U. S. 307 (99 SC 2781, 61 LE2d 560); Loumakis v. State, 179 Ga. App. 294, 299 (8) (346 SE2d 373).
Judgment affirmed.
